How big is the universe??

Question

I know that the universe expands and gets bigger every day but I wanna see how good of a round about guess I can get.

Answer 1

Theoretically infinite.

In cosmological terms, the universe is thought to be a finite or infinite space-time continuum in which all matter and energy exist. Some scientists hypothesize that the universe may be part of a system of many other universes, known as the multiverse. Infinite is somewhat acceptable to most who believe in God, since it correlates with the concept of God as infinite.

A multiverse (or meta-universe) is the hypothetical set of multiple possible universes (including our universe) that together comprise all of physical reality. The structure of the multiverse, the nature of each universe within it and the relationship between the various constituent universes, depend on the specific multiverse hypothesis considered.

Multiverses have been hypothesized in physics, philosophy, and fiction, particularly in science fiction. The specific term "multiverse", which was originally coined by William James, was popularised by science fiction author Michael Moorcock. In these contexts, such terms as "alternate universes", "parallel universes", or "parallel worlds" may often be used.

The possibility of many universes raises various scientific, philosophical, and theological questions.

In practical terms, the "known" universe is as big as the farthest object viewed from earth. Hubble saw images that reveal galaxies billions of light years away

Answer 2

That depends. If we're assuming that the universe has no limit and has a stable size, then the volume of the universe is infinite. If the universe is contracting, then there is no way to know the current volume of the universe as we can't determine the point of contractions. If we are to assume that the universe is expanding, however, then we can make a somewhat decent guess on its volume. We may be able to assume that the universe is expanding at the speed of light, or 1,079,252,848.8km/hr. The current consensus is that the universe is about 13,700,000,000 years old. That equates to 120,012,000,000,000 (12.012 trillion) hours. That means that the radius of the universe is 129,523,292,890,185,600,000,000 (129.5 sextillion) kilometres. The volume of a sphere (which can be guessed as the universe's shape) can be found using V=(4/3)πr³. If we can assume all of these things, then we can approximate the volume of the universe to be about 9.1018961*10^69 km³. Pretty big, huh?

Answer 3

incredibly no longer likely. at the same time as fairly available that our universe is just one universe in a multiverse of alternative universes, it quite is not likely we are an atom or atoms in a macro universe the place we are only debris. Quantum mechanics shows that typical debris like quarks and electrons all have the comparable mass, charge and spin. subsequently the electron on the tip of your finger has the right mass as an electron in a stars corona ten billion easy years from right here. And the charge of an up quark forming the proton of an atom making up the better right pixel of your laptop’s demonstrate screen is strictly the comparable through fact the single as an up quark interior the Orion nebula. interior the observable universe stars, galaxies, planets all have diverse a lot, magnetic fields, etc. For us to be typical debris in a macro universe it would must be tremendously risky.

Answer 4

The observable Universe is about 10 billion light years in radius.

Answer 5

it is my understanding that the universe folds back in on itself. There is a finite amount of stuff in it, but with our ablilties of perception, if we go "out" far enough, we'd come back.

like if a two-dimension person were walking around on a sphere,
it would be endless,
but a 3d person could see it for what it was.

we are limited in scope and power.

Answer 6

Start counting. Continue counting forever. That's how many miles the universe is large.

Answer 7

there is no practical figure about how big the universe is .. i had a similar question on this but i forgot the details

Answer 8

RRRRReally Bigggggggggg.

Say for instance 3,000,000,000 Light Years to the fartherest known thing, and that is not the end of it.
I

Answer 9

trillons of light years. or more. the size really dosent matter because anything beyond the universe is nothingness

Answer 10

No one can imagine how big is universe because it is so big that it is unimaginable.
